Genet manufactures various types and models of corrugated compensators

Corrugated compensator is also customarily called expansion joint or expansion joint. It consists of bellows (an elastic element) that constitutes its working body and accessories such as end tubes, brackets, flanges, and conduits. Mainly used in various pipelines, it can compensate for the thermal displacement, mechanical deformation and absorb various mechanical vibrations of the pipeline, thereby reducing the deformation stress of the pipeline and increasing the service life of the pipeline. The connection methods of corrugated compensator are divided into two types: flange connection and welding. Directly buried pipeline compensators generally adopt welding methods (except for trench installation). Working principle The corrugated compensator is used to utilize the effective expansion and contraction deformation of the elastic components of the corrugated compensator to absorb the thermal expansion and contraction of pipelines, conduits or containers caused by thermal expansion and contraction. A compensation device for dimensional changes, belonging to a compensation element. Can absorb axial, lateral, and angular displacement.
Failure analysis The manufacturer's analysis of the failure reasons of the bellows compensator found that the failure during operation mainly manifests itself in two forms: corrosion leakage and instability deformation, among which corrosion failure is the most common. From the anatomical analysis of corrosion-failed corrugated expansion joints (compensators), it is found that corrosion failures are usually divided into pitting corrosion perforations and stress corrosion cracking, of which chloride ion stress corrosion cracking accounts for approximately the entire corrosion failure. Therefore, the safety and reliability of the corrugated expansion joint (compensator) can be greatly improved by correctly selecting the material and structure of the corrugated pipe, reasonably designing the waveform parameters and fatigue life, and ensuring the installation quality. In design, the stability of the compensator should be considered to prevent bellows instability. The data shows that the compensation amount of the bellows depends on its fatigue life. The higher the fatigue life, the smaller the single wave compensation amount of the bellows. When the bellows design has a low allowable service life, not only its meridional comprehensive stress is high, but also the circumferential stress is relatively high, causing the bellows to quickly enter plastic deformation locally, causing the bellows to become unstable and cause failure.
